Difference equations, determinants and the Secret Santa problem
Keyword(s):
In [1] it is shown that every second-order linear difference equation with, in general, variable coefficients can be reduced to the formIt is also shown that (1) can be solved explicitly provided that a particular solution a (n) of the ‘auxiliary equation’can be found, and many cases in which a solution of (2) is available are discussed. However, [1] is defective in that no method of finding a solution of (2) in the general case is given.
